Version: 1.5.93 (using KDE 3.1.93 (3.2 beta 1), compiled sources) Compiler: gcc version 3.3.2 (Debian) OS: Linux (i686) release 2.6.0-test9 Link handling in the composer window in kmail 1.5.93 has improved, but this link is broken across two lines after the % character. Even enclosing the whole link in <..> characters doesn't help. http://www.mail-archive.com/video4linux-list%40listman.redhat.com/msg06262.html
We'll inform Trolltech about this (if it's reproducible with Qt 3.2.3). It's no bug in KMail, so I close your report as invalid.
